Jewell LILY Self-Leveling Borehole Tiltmeter

LILY is the culmination of over 25 years of experience in the fields of instrumentation and geophysics. We developed LILY for volcanic and tectonic research, ocean bottom applications, and for monitoring of hydraulic fracturing and other subsurface processes in the mining and petroleum industries.

LILY ‘s high-pressure stainless steel housing is rated for submergence to depths of 3500 meters. You can attain even greater depths by switching to a titanium housing. The tilt sensors in LILY can self-level on command through a range of ±10 degrees and have 5 nanoradians resolution over a dynamic range of ±330 microradians. The self-leveling feature keeps LILY on scale indefinitely at the high gains required for geophysical work. Its versatile RS232 and RS422 serial outputs, and its powerful firmware command set, give you a wide range of measurement and recording options. Data can be stored internally for periodic downloading, or streamed to your external network or recorder. GPS compatible output formats are included.
